If all goes smoothly, Symba will soon be shedding the pounds and be well on his way to living life to fullest. To help him get there, he's now accepting applications for a new best friend — one who'll keep him on the right track.

"Symba needs a home where his adopter will be diligent with an exercise and diet program that will help get this big guy to a healthy weight," the shelter said.
